<P>PROBLEM TO BE SOLVED: To provide a transmission device for a work vehicle capable of dispensing with an expensive motor necessary for a large torque, capable of reducing production and part costs, capable of individually driving front wheels (6) corresponding to a travelling state such as slippage or the like, and improving the safety and operability of the vehicle. <P>SOLUTION: The rotating force of an engine 1 is transmitted via a transmission 2 for travel to rear wheels 4 to drive them and the rotating force is transmitted to a PTO axis 5 protruding from a vehicle body to drive it. The rotating force is transmitted to a battery 22 to charge it and to drive a variable motor 7 by electric power stored in the battery 22 to drive the front wheels 6 by the transmission route different from the transmission route leading from the engine 1 to the rear wheel 4. Furthermore, sensors 25, 26, 27 to detect the number of rotations of the front wheels and the rear wheels are provided to control the rotations of the front wheels 6 corresponding to the rotations of the rear wheels 27. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
